Scientific realists claim we can justifiably believe that science is getting at the truth. But they have long faced historical challenges: various episodes across history appear to demonstrate that even strongly supported scientific theories can be overturned and left behind. In response, realists have developed new positions and arguments. As a result of specific challenges from the history of science, and realist responses, we find ourselves with an ever increasing data-set bearing on the (possible) relationship between science and (...) truth. The present volume introduces new historical cases impacting the debate, and advances the discussion of cases that have only very recently been introduced. At the same time, shifts in philosophical positions affect the very kind of case study that is relevant. Thus the historical work must proceed hand in hand with philosophical analysis of the different positions and arguments in play. It is with this in mind that the volume is divided into two sections, entitled “Historical cases for the debate,” and “Contemporary scientific realism”. All sides agree that historical cases are informative with regard to how, or whether, science connects with truth. Defying proclamations as early as the 1980s announcing the death knell of the scientific realism debate, here is that rare thing: a philosophical debate making steady and definite progress. Moreover, the progress it is making concerns one of humanity’s most profound and important questions: the relationship between science and truth, or, put more boldly, the epistemic relation between humankind and the reality in which we find ourselves.

This book offers a close and rigorous examination of the arguments for and against scientific realism and introduces key positions in the scientific realism/antirealism debate, which is one of the central debates in contemporary philosophy of science. On the one hand, scientific realists argue that we have good reasons to believe that our best scientific theories are approximately true because, if they were not even approximately true, they would not be able to explain and predict (...) natural phenomena with such impressive accuracy. On the other hand, antirealists argue that the success of science does not warrant belief in the approximate truth of our best scientific theories. This is because the history of science is a graveyard of theories that were once successful but were later discarded. The author eventually settles on a middle ground position between scientific realism and antirealism called "relative realism.". (shrink)

This book is about the methods used for unifying different scientific theories under one all-embracing theory. The process has characterized much of the history of science and is prominent in contemporary physics; the search for a 'theory of everything' involves the same attempt at unification. Margaret Morrison argues that, contrary to popular philosophical views, unification and explanation often have little to do with each other. The mechanisms that facilitate unification are not those that enable us to (...) explain how or why phenomena behave as they do. A feature of this book is an account of many case studies of theory unification in nineteenth- and twentieth-century physics and of how evolution by natural selection and Mendelian genetics were unified into what we now term evolutionary genetics.

The six essays in this volume discuss philosophical thought on scientific theory including: a call for a realist, rather than instrumentalist interpretation of science; a critique of one of the core ideas of positivism concerning the relation between observational and theoretical languages; using aerodynamics to discuss the representational aspect of scientific theories and their isomorphic qualities; the relationship between the reliability of common sense and the authenticity of the world view of science; removing long-held ambiguities on the (...) theory of inductive logic; and the relationship between the actuality of conceptual revolutions in the history of science and traditional philosophical pictures of scientific theory-building.

This book analyzes the philosophical foundations of sensorimotor theory and discusses the most recent applications of sensorimotor theory to human computer interaction, child's play, virtual reality, robotics, and linguistics. -/- Why does a circle look curved and not angular? Why doesn't red sound like a bell? Why, as I interact with the world, is there something it is like to be me? These are simple questions to pose but more difficult to answer. An analytic philosopher might respond to (...) the first by merely observing, ``if we ponder the concept `circle' we find that it is the essence of a circle to be round''; but where does this definition come from? Was it set in stone by the gods, the divine arbiters of circle-ness (red-ness and conscious-ness)? It is a measure of the importance of Kevin O'Regan and Alva Noe's 2001 paper `A sensorimotor account of vision and visual consciousness' that it reveals deep scientific and philosophical insight on these foundational issues of perception. -/- Opening with a chapter from Kevin O'Regan, this collection of new essays continues by presenting fifteen additional essays on as many developments achieved in recent years in this field. It provides readers with a critical review of the sensorimotor theory and in so doing introduces them to a radically new approach in cognitive science. (shrink)

According to the semantic view, a theory is characterized by a class of models. In this paper, we examine critically some of the assumptions that underlie this approach. First, we recall that models are models of something. Thus we cannot leave completely aside the axiomatization of the theories under consideration, nor can we ignore the metamathematics used to elaborate these models, for changes in the metamathematics often impose restrictions on the resulting models. Second, based on a parallel between van (...) Fraassen’s modal interpretation of quantum mechanics and Skolem’s relativism regarding set-theoretic concepts, we introduce a distinction between relative and absolute concepts in the context of the models of a scientific theory. And we discuss the significance of that distinction. Finally, by focusing on contemporary particle physics, we raise the question: since there is no general accepted unification of the parts of the standard model (namely, QED and QCD), we have no theory, in the usual sense of the term. This poses a difficulty: if there is no theory, how can we speak of its models? What are the latter models of? We conclude by noting that it is unclear that the semantic view can be applied to contemporary physical theories. (shrink)

Philosophers of science have long been concerned with these questions. In the 1980s, influential work by Clark Glymour, Michael Friedman, John Watkins, and Philip Kitcher articulated general accounts of theory unification that attempted to underwrite a connection between unification, truth, and understanding. According to the ‘unifiers,’ as we may call them, a theory is unified to the extent that it has a small theoretical structure relative to the domain of phenomena it covers, and there are general syntactic criteria (...) that allow one to determine how unified a theory is. The explanatory power of a theory, and the understanding of nature it gives us, is a direct consequence of this unity. As well, the more unified a theory is, the better confirmed it will be, and under some conditions a theory’s unity can justify realism about unobservable entities posited by it. In the 1990s disunity became the dominant theme, with books such as John Dupré’s The Disorder of Things and the Galison and Stump anthology arguing that it is a mistake to view science as a unified practice and that rather than an epistemic virtue, unification in science is a metaphysical vice.

We live in a period of unprecedented intermixtures of forms of expression. The traditional contrasting of science to art and of the exact sciences to the humanities is becoming obsolete. Today "All has become mixed up in the Oblonskii household": where one thing ends and another begins is impossible to determine. Mathematical methods are penetrating literature studies, musical theory, and the like. Such strange disciplines as, for example, "artmetrics" are arising at the point of contact between the exact sciences (...) and humanities. Digital computers "compose" perfectly good music, write verse , create original works in decorative art, and so forth. (shrink)

The topic of the presence, legitimacy and epistemic worth of narrative explanations in different kinds of scientific discourse has already enjoyed several revivals within related discussions in contemporary philosophy of science. In fact, we have recently witnessed a more extensive, more unprejudiced and ambitious attention to narrative modes of making science. I think we need a systematic theoretical framework in order to categorize these different functions of narratives and understand their role in scientific explanatory and justificatory practice. (...) My claim is that some distinctions and analytic tools developed within the field of contemporary Argumentation Theory might be of help. (shrink)

This impressive volume presents the results of a symposium on the structure of scientific theories held at the University of Illinois, Urbana, on March 26-29, 1969; lest this create the wrong impression, let it be noted at the outset that the volume is much more than a collection of papers. Indeed, when one takes into account Frederick Suppe’s book-length introduction, the editing of the critical comments, the extensive bibliography, and the fine index, the work must be seen as the (...) best account of scientific theory now available, one that surely commends itself to every philosopher of science with the slightest interest in metaphysics. The thrust of the symposium was to examine the view of scientific theories that has enjoyed great vogue among logical positivists, who have seen such theories as "axiomatic calculi in which theoretical terms and statements are given a partial observational interpretation by means of correspondence rules." Suppe refers to this as the "Received View," although it has been increasingly questioned in recent years, particularly by philosophers who have some proficiency in the history of science and by scientists who question its fidelity to actual scientific practice. One of the major aims of the symposium was to subject the Received View to analysis and debate by its proponents and by its critics, to assess its present status, and to see if any consensus has begun to develop on this topic—which plays such a key role in the philosophy of science. Suppe performs the analytic function in his critical introduction, and Stephen Toulmin adds a postscript that attempts to chart a course for future research. The message seems to be that the Received View has run its course and has proved to be more a hindrance than a help to philosophizing about science; what will take its place, however, does not emerge with any clarity. Participants in the symposium include all the luminaries in the philosophy of science movement: Carl Hempel, Patrick Suppes, David Bohm, Hilary Putnam, Thomas Kuhn, and Dudley Shapere, among others. Especially noteworthy are Suppe’s account of the development of the Received View and the criticisms that have been lodged against it, viz., its reliance on the analytic-synthetic distinction; the tenability of the observational-theoretical distinction; the notion of partial interpretation; its failure to include models as integral components; its analysis of correspondence rules; and its reliance on axiomatization. Suppe also details some of the proposed alternatives to the Received View, giving in the process lucid expositions of the thought of Toulmin, Kuhn, Hanson, Popper, and Feyerabend—all of which he treats under the rubric of "Weltanshauungen [[sic]] Analyses." Those interested in the relationships between history of science and philosophy of science will find the interchange between I. Bernard Cohen and Peter Achinstein stimulating as well as illuminating. Kuhn takes this occasion to offer his "Second Thoughts on Paradigms," and Shapere continues his criticism of both Kuhn and logical positivism—now more constructively than heretofore—with a penetrating essay entitled "Scientific Theories and their Domains." About the only thing that is lacking is a treatment of recent developments in England, particularly the work of Rom Harré at Oxford and related thinkers, who likewise reject the Received View and offer interesting alternatives to it that have yet to be appreciated and critiqued in the U.S.—W.A.W.

According to both traditional positivist approaches and also to the sociology of scientific knowledge, social analysts should not themselves become involved in the controversies they are investigating. But the experiences of the authors in studying contemporary scientific controversies—specifically, over the Australian Animal Health Laboratory, fluoridation, and vitamin C and cancer—show that analysts, whatever their intentions, cannot avoid being drawn into the fray. The field of controversy studies needs to address the implications of this process for both (...) class='Hi'>theory and practice. (shrink)

This volume is the first systematic and thorough attempt to investigate the relation and the possible applications of mereology to contemporary science. It gathers contributions from leading scholars in the field and covers a wide range of scientific theories and practices such as physics, mathematics, chemistry, biology, computer science and engineering. Throughout the volume, a variety of foundational issues are investigated both from the formal and the empirical point of view. The first section looks at the topic as (...) it applies to physics. The section addresses questions of persistence and composition within quantum and relativistic physics and concludes by scrutinizing the possibility to capture continuity of motion as described by our best physical theories within gunky space times. The second part tackles mathematics and shows how to provide a foundation for point-free geometry of space switching to fuzzy-logic. The relation between mereological sums and set-theoretic suprema is investigated and issues about different mereological perspectives such as classical and natural Mereology are thoroughly discussed. The third section in the volume looks at natural science. Several questions from biology, medicine and chemistry are investigated. From the perspective of biology, there is an attempt to provide axioms for inferring statements about part hood between two biological entities from statements about their spatial relation. From the perspective of chemistry, it is argued that classical mereological frameworks are not adequate to capture the practices of chemistry in that they consider neither temporal nor modal parameters. The final part introduces computer science and engineering. A new formal mereological framework in which an indeterminate relation of part hood is taken as a primitive notion is constructed and then applied to a wide variety of disciplines from robotics to knowledge engineering. A formal framework for discrete mereotopology and its applications is developed and finally, the importance of mereology for the relatively new science of domain engineering is also discussed.

This chapter explores the main argument for scientific realism, the No-Miracle Argument (NMA), and two antirealist arguments criticizing scientific realism, the Pessimistic Induction and the argument from Underdetermination. Scientific realists have articulated many different versions of their doctrine in response to the acknowledged shortcomings of the original NMA. While most rely on an inference to the best explanation, they propose stricter notions of novel predictive success, richer notion of success in general, and more discriminating ways of identifying (...) the parts of a theory responsible for that success. When one looks at the history of science, especially the scientific revolutions in physics, astronomy, and chemistry chronicled in T. S. Kuhn, the realist seems to be in a bind. For Kuhn, and later Larry Laudan, gave many examples of theories that were successful in their day and recognize as based on radically false assumptions about the world. (shrink)

During the Second World War, the Allies faced a question colloquially known as the “German Tank Problem”: how many tanks will the Axis ever produce? The answer resulted from an elegant probabilistic argument which was used by Allied mathematicians to make successful upper-bound estimates for the total Axis tank production. This paper shows that if two empirical postulates are true of the history of science, a parallel argument can be used to come up with lower-bound estimates for the number of (...) alternative scientific theories that remain undiscovered. The lower bound in question increases proportionally with the number of theories that have already been discovered. So, the problem of underconsideration is a serious problem and it will get worse, not better, as we discover new theories. (shrink)

Notions of uniform and gradual evolution have been replaced in some circles by biological and paleontological models that postulate that periods of rapid change punctuate long periods of evolutionary stasis. This new theory, called punctuated equilibria (or PE for short), may have implications for paradigms in scholarly disciplines other than the sciences. Whereas old evolutionary models exerted great influence upon historians, sociologists, anthropologists, and students of religion for more than a century, the new model may provide heuristic paradigms for (...) research that correlate more adequately with the current observations of scholars. We therefore provide suggestions for deployment of this new scientific paradigm in history and anthropology. In particular, this model can explain the rise of the Israelite state and the religious ethos in the Hebrew Bible, two major concerns of today's socioscientific study of biblical materials. Thus the possibility of an overarching paradigm for the social sciences is entertained. (shrink)

This book brings together a series of papers presented at the 1953 meeting in Boston of the American Association for the Advancement of Science and published in various issues of The Scientific Monthly. The papers deal with the criteria for scientific theories, operationalism, psychoanalysis, organism and machine, and science as a social and historical phenomenon. The contributors are particularly well-chosen. -- D. R.

Consciousness, with its irreducible subjective character, was almost exclusively a philosophical topic until relatively recently. Today, however, the problem of explaining the felt quality of experience has also become relevant to science and engineering, including robotics and AI: “What would we have to build into a robot so that it really felt the touch of a finger, the redness of red, or the hurt of a pain?”(O’Regan, 2014, p. 23). Yet a practical response still requires an adequate theory of (...) consciousness,which brings us back to the hard problem: how can we account, from a scientific point of view, for thephenomenological character of experience? Over a decade ago,O’Regan and Noë (2001)proposeda new approach to these questions, the so-called sensorimotor approach to perceptual experience.How far has this approach come and what are its outstanding challenges? The volumeContemporarySensorimotor Theory, edited by Bishop and Martin, takes stock of the current state of the field. (shrink)

This paper examines the status and role of modes of explanation of behavior in contemporary legal theory. It does so by reference to the criticism made by Sundram Soosay of the dominance of the conscious and deliberative mode of explanation in the work of Joseph Raz, H.L.A. Hart and Ronald Dworkin. Soosay's criticism is discussed and evaluated by reference to a reading of these three theorists. I argue for a pluralist and pragmatic approach to modes of explanations of (...) behavior, as opposed to one that conceives of representations of behavior as capable of offering true and verifiable descriptions of human nature. I illustrate the value of such pluralism and pragmatism by reference to Institutions of Law, the most recent work by Neil MacCormick. Ultimately, I call for a closer engagement by legal theorists with the issues taken up by the philosophy of the social sciences, and in particular, on its treatment of the question of the status and role of modes of explanation of behavior for the purpose of proposing social scientific hypotheses.

Jaakko Hintikka (1998) has argued that clarifying the notion of abduction is the fundamental problem of contemporary epistemology. One traditional interpretation of Peirce on abduction sees it as a recipe for generating new theoretical discoveries . A second standard view sees abduction as a mode of reasoning that justifies beliefs about the probable truth of theories. While each reading has some grounding in Peirce's writings, each leaves out features that are crucial to Peirce's distinctive understanding of abduction. I develop (...) and defend a third interpretation, according to which Peirce takes abductive reasoning to lead to judgments about the relative pursuitworthiness of theories; conclusions that can be thoroughly disconnected from assessments of truth-value. Even if Peirce's use of "abduction" slides around among each of these three importantly different though potentially compatible senses, this neglected third understanding makes sense of a large number of Peirce's remarks and directs our attention to the cognitive structure of judgments that scientists face after the initial proposal of explanatory hypotheses but prior to their experimental testing; a topic which should be of interest to contemporary philosophers of science.

One of the vividly discussed topics in the contemporary philosophy of science (especially physics) is the opposition between realism and Anti-Realism. The supporters of the first way of thinking trust in the objective existence of realities studied by science. They consider theories as approximate descriptions of these realities (Psillos 1999, xvii), whereas their opponents do not. However, both sides base their argumentation on simplified notions of scientific theories. In this paper, we present a more general approach, which can (...) be coined as “Theoretical Physics Realism” (TPR). It is based on the detailed reconstruction of the polysystemic nature of physical theories. The consequences of this reconstruction for understanding the genuine relationship between theories and experiments in studying the realities are indicated. The paper distinguishes between abstract (general) and domain-dependent theories and appeals to specific physical theories together with their application domains rather than to general speculations.

The rationality of scientific concept formation in theory transitions, challenged by the thesis of semantic incommensurability, can be restored by theChains of Meaning approach to concept formation. According to this approach, concepts of different, succeeding theories may be identified with respect to referential meaning, in spite of grave diversity of the mathematical structures characterizing them in their respective theories. The criterion of referential identity for concepts is that they meet a relation ofsemantic embedding, i.e. that the embedding concept (...) can be substituted by the embedded one in classical limit situations. Three case studies from contemporary physics theories will be used to show that the Chains of Meaning approach not only yields meaning comparisons for already established concepts (as for Newtonian and Schwarzschild mass) but is also well suited to characterize actual scientific strategies of concept formation in yet open cases such as black hole entropy or relativistic thermodynamics.

In this paper, I argue that the role of values in theory selection is an important issue within medical education. I review the underdetermination argument, which is the idea within philosophy of science that the data serving as evidence for theories are by themselves not sufficient to support a theory to the exclusion of alternatives. There are always various explanations compatible with the data, and we ultimately appeal to certain values as our grounds for choosing one theory (...) over another. I explore some of the ways contemporary feminist philosophers have chosen to grapple with the problem of underdetermination and proposed solutions to systematize how values might be incorporated into theory choice, drawing primarily from the work of Helen Longino and Elizabeth Anderson. I conclude by discussing how value‐laden inquiry should be incorporated within medical education to promote reflection towards medicine’s normative underpinnings. (shrink)

How can we best understand the major debates and recent movements in contemporary empirical political theory? Is there a human nature on which we can construct scientific theories of political life? What is the role of culture in shaping any such nature? How objective and value-free can political theories be? These are only a few of the issues addressed by this collection of essays from a disparate group of contributors.

Reflection without Rules offers a comprehensive, pointed exploration of the methodological tradition in economics and the breakdown of the received view within the philosophy of science. Professor Hands investigates economists' use of naturalistic and sociological paradigms to model economic phenomena and assesses the roles of pragmatism, discourse, and situatedness in discussions of economic practice before turning to a systematic exploration of more recent developments in economic methodology. The treatment emphasizes the changes taking place in science theory and its relationship (...) to the movement away from a rules-based view of economic methodology. The work will be of interest to all economists concerned with methodological issues as well as philosophers and others studying the relationships between economics and contemporary science theory.

Scientific realism is a thesis about the success of science. Most traditionally: science has been so successful at prediction and guiding action because its best theories are true (or approximately true or increasing in their degree of truth). If science is in the business of doing its best to generate true theories, then we should turn to those theories for explanatory knowledge, predictions, and guidance of our actions and decisions. Views that are popular in contemporary philosophy of science (...) about scientific modeling and the centrality of idealization create several challenges for this traditional form of scientific realism. Yet the basic idea behind scientific realism that science has been and will continue to be epistemically successful is deeply appealing. This chapter explores the challenges posed by idealization and scientific modeling to motivate a scientific realism fully divorced from the idea that science is in the business of generating true theories. On the resulting view, the objects of scientific knowledge are causal patterns, so this knowledge only ever provides partial, simplified accounts of a complex reality. This variety of selective realism better accommodates the nature of our present-day scientific successes and offers an interpretation of scientific progress that resists the antirealist’s pessimism.

The appearance of consciousness in the universe remains one of the major mysteries unsolved by science or philosophy. Absent an agreed-upon definition of consciousness or even a convenient system to test theories of consciousness, a confusing heterogeneity of theories proliferate. In pursuit of clarifying this complicated discourse, we here interpret various frameworks for the scientific and philosophical study of consciousness through the lens of social insect evolutionary biology. To do so, we first discuss the notion of a forward test (...) versus a reverse test, analogous to the normal and revolutionary phases of the scientific process. Contemporary theories of consciousness are forward tests for consciousness, in that they strive to become a means to classify the level of consciousness of arbitrary states and systems. Yet no such theory of consciousness has earned sufficient confidence such that it might be actually used as a forward test in ambiguous settings. What is needed now is thus a legitimate reverse test for theories of consciousness, to provide internal and external calibration of different frameworks. A reverse test for consciousness would ideally look like a method for referencing theories of consciousness to a tractable model system. We introduce the Ant Colony Test as a rigorous reverse test for consciousness. We show that social insect colonies, though disaggregated collectives, fulfill many of the prerequisites for conscious awareness met by humans and honey bee workers. A long lineage of philosophically-neutral neurobehavioral, evolutionary, and ecological studies on social insect colonies can thus be redeployed for the study of consciousness in general. We suggest that the ACT can provide insight into the nature of consciousness, and highlight the ant colony as a model system for ethically performing clarifying experiments about consciousness.

The philosopher dealing with problems of the epistemology and logic of scientific knowledge cannot disregard those truly immense changes that have occurred in science in the present century. Moreover, he must interest himself not only in what has been learned in the objective world that is new, but by what new methods and means this knowledge has been acquired, how its structure has changed, what categories define the essence of contemporary scientific theorizing, and its outreach into cognition (...) in the future. Of course, the character, structure, and methods of the scientific acquisition of knowledge are determined in the final analysis by what it is that is being cognized, what things and processes are coming to be known. However, direct influence upon logical concepts in the theory of knowledge is brought to bear in the very process of cognition, in its methods and means of approaching the reflection of the object.

One of Descartes’ greatest contributions to modern thought lies in his dualistic conception of mind and body. While the physical body in Descartes assumes a passive role in the ontological structure of reality, subject to mechanistic laws, the mind in Descartes, on the other hand, assumes an active role, as an organizing axis and producer of values and ideas, exercising a rational dominion over reality. physical reality. This dualistic Cartesian conception would generate important effects on the problem of mind-body interaction, (...) becoming the central theme debated by contemporary philosophy of mind. Contemporary theories of philosophy of mind seek to overcome this dualism, through neuroscience and cognitive psychology. These theories attempt to apply the reductionist scientific model to human mental phenomena and processes, describing them in non-mental, physical, and empirical terms. However, the reductionist project of these contemporary theories has not yet proved successful in explaining unobservable phenomena of the mind, such as consciousness, will and human subjectivity.

Comments on the review by Stephen Yanchar of the current author's book, "Behavior and Personality: Psychological Behaviorism." The past fifteen years has seen an accelerating growth of interest in psychology's fragmentation and the importance of unification, in a manner that did not exist before. Stephen Yanchar is one of the contemporary leaders in the unification movement, with a focus on philosophy, to which he has been contributing important works. Yanchar's philosophy , fundamental understanding of what psychology is and should (...) be, conception of unifying psychology and, as we will see, his agenda for the field of theoretical and philosophical psychology, are quite different from those of my philosophy of unified positivism and theory of psychological behaviorism . Thus, although this has not been made clear, Yanchar's review is based on a philosophical position that really does not accept psychology as a science. 2012 APA, all rights reserved). (shrink)

Philosophers of science readily acknowledge that nonepistemic values influence the discovery and pursuit of scientific theories, but many tend to regard these influences as epistemically uninteresting. The present paper challenges this position by identifying three avenues through which nonepistemic values associated with discovery and pursuit in contemporary pollution research influence theory appraisal: (1) by guiding the choice of questions and research projects, (2) by altering experimental design, and (3) by affecting the creation and further investigation of theories (...) or hypotheses. This analysis indicates that the effects of these values are sufficiently complex and epistemically significant to merit further attention. †To contact the authors, please write to: Kevin Elliott, Department of Philosophy, University of South Carolina, Columbia, SC 29208; e‐mail: [email protected] .

Nineteenth-century optical toys that showcase illusions of motion such as the phenakistoscope, zoetrope, and praxinoscope, have enjoyed active “afterlives” in the twentieth and twenty-first centuries. Contemporary incarnations of the zoetrope are frequently found in the realms of fine art and advertising, and they are often much larger than their nineteenth-century counterparts. This article argues that modern-day optical toys are able to conjure feelings of wonder and spectacle equivalent to their nineteenth-century antecedents because of their adjustment in scale. Exploring a (...) range of contemporary philosophical toys found in arts, entertainment, and advertising contexts, the article discusses various technical adjustments made to successfully “scale up” optical toys, including the replacement of hand-spun mechanisms with larger sources of motion and the use of various means such as architectural features and stroboscopic lights to replace traditional shutter mechanisms such as the zoetrope’s dark slots. Critical consideration of scale as a central feature of these installations reconfigures the relationship between audience and device. Large-scale adaptations of optical toys revise the traditional conception of the user, who is able to tactilely manipulate and interact with the apparatus, instead positing a viewer who has less control over the illusion’s operation and is instead a captive audience surrounded by the animation. It is primarily through their adaptation of scale that contemporary zoetropes successfully elicit wonder as scientific spectacles from their audiences today. (shrink)

This book successfully achieves to serve two different purposes. On the one hand, it is a readable physics-based introduction into the philosophy of science, written in an informal and accessible style. The author, himself a professor of physics at the University of Notre Dame and active in the philosophy of science for almost twenty years, carefully develops his metatheoretical arguments on a solid basis provided by an extensive survey along the lines of the historical development of physics. On the other (...) hand, this book supplies one long argument for Cushing´s own attitude in the philosophy of science. While former studies of the author, from which this book draws in part, focused each on one special episode in the history of science, this book gathers case material from many different parts of physics and epochs. The main goal of this book is ”to impress upon the reader the essential and ineliminable role that philosophical considerations have played in the actual practice of science” (p. xv). The book is beautifully edited and produced; it contains a wealth of illustrative figures, well-chosen short quotations from original sources and contemporary commentators (some longer quotations are relegated in an appendix at the end of a chapter) and does not dispense with insightful mathematical arguments in the main text (some advanced deductions are, however, relegated in the appendices). It contains nine parts, whereas only the first and the last one are exclusively devoted to philosophical issues. The seven remaining parts, each subdivided into three chapters, centre around one major episode (a theory, a world view, etc.) in the history of physics. The author presents this material in a clear and philosophically unbiased way so that also readers who do not share Cushing’s subsequent philosophical conclusions will find this inspiring book extremely useful. Part 1 (”The scientific enterprise”) discusses some traditional (”objectivist”) views concerning the status of scientific knowledge, ”the” scientific method, and the relation.... (shrink)

In many scientific fields, sparseness and indirectness of empirical evidence pose fundamental challenges to theory development. Theories of the evolution of human cognition provide a guiding example, where the targets of study are evolutionary processes that occurred in the ancestors of present-day humans. In many cases, the evidence is both very sparse and very indirect (e.g., archaeological findings regarding anatomical changes that might be related to the evolution of language capabilities); in other cases, the evidence is less sparse (...) but still very indirect (e.g., data on cultural transmission in groups of contemporary humans and non-human primates). From examples of theoretical and empirical work in this domain, we distill five virtuous practices that scientists could aim to satisfy when evidence is sparse or indirect: (i) making assumptions explicit, (ii) making alternative theories explicit, (iii) pursuing computational and formal modelling, (iv) seeking external consistency with theories of related phenomena, and (v) triangulating across different forms and sources of evidence. Thus, rather than inhibiting theory development, sparseness or indirectness of evidence can catalyze it. To the extent that there are continua of sparseness and indirectness that vary across domains and that the principles identified here always apply to some degree, the solutions and advantages proposed here may generalise to other scientific domains.

These books make significant contributions to contemporary realism. Psillos’s book presents an excellent overview of the central components of current scientific realism, the main challenges to it, and the most promising strategies for defending it. It is a work of remarkable clarity, synthesis, and argumentative rigor. Psillos’s realism is committed to three claims: Scientific theories make irreducible assertions about unobservable entities which are literally true or false ; In the case of mature, successful theories, their success provides (...) good reason for taking their assertions about unobservables to be true, or approximately so ; and What makes scientific theories true or false is the mind-independent natural-kind structure of reality.

White's dense article on narrative discusses the ways that different groups of 20th century historians, particularly historical theorists (see pp.8-9), have constructed and deconstructed narrative as a means of communicating history. White himself acknowledges that narrativity challenges the scientific of history, but suggests that narrativity is not only unavoidable, but also offers a form of literary or allegorical truth.\n\nWhite first discusses the critiques of narrative as a means of communication--it focuses too heavily on political players, it is "unscientific," it (...) is inherently limited because narrative itself cannot be objective (although it's authors sometimes claim it to be).\n\nHe then moves on to discuss other, heavily theoretical, takes on why narrative is still useful as a means of historical communication: that narrative works because it performs as a trope which readers can easily recognize from myth and fiction, or, that narrative works because it allows us to transform events from the present to a synthesized past.\n\nWhite's article is difficult to read, but important background for anyone who wants to see what people have said about narrative in the past 100 years--and why it is still important.

In this article, I present a critical literature study of the theoretical approach of practical theologians in South Africa to our discipline, in honour of Yolanda Dreyer on her 60th birthday. Some of my colleagues' approaches at the universities of Stellenbosch, Free State, Pretoria, Unisa and NWU are discussed. All of them work with practical theological hermeneutics. The basic hermeneutic approach of Daniël Louw is widened with an integrated approach by Richard R. Osmer in which practical theology as a hermeneutic (...) discipline also includes the empirical aspect which the action theory approach has contributed to the discussion. After discussing Louw's basic hermeneutic approach, all the other colleagues who basically accepted Osmer's approach in their publications are discussed. Important and new ground is being broken by contemporary colleagues, including research in public practical theology, without neglecting the focus on Christian congregations, and new work is being done at the grass roots level of African issues in our country.

Many opinions and ideas about aging exist. Biological theories have taken hold of the popular and scientific imagination as potential answers to a “cure” for aging. However, it is not clear what exactly is being cured or whether aging could be classified as a disease. Some scientists are convinced that aging will be biologically alterable and that the human lifespan will be vastly extendable. Other investigators believe that aging is an elusive target that may only be “statistically” manipulatable through (...) a better understanding of the operational principles of systems situated within complex environments. Not only is there confusion over definitions but also as to the safety of any potential intervention. Curing cell death, for example, may lead to cell cancer. The search for a cure for aging is not a clearly beneficial endeavour. This paper will first, describe contemporary ideas about aging processes and second, describe several current life extension technologies. Third, it analyses these theories and technologies, focusing on two representative and differing scientific points of view. The paper also considers the public health dilemma that arises from life extension research and examines two issues, risk/benefit ratio and informed consent, that are key to developing ethical guidelines for life extension technologies.

Alan Musgrave is one of the foremost contemporary defenders of scientific realism. He is also one of the leading exponents of Karl Popper’s critical rationalist philosophy. In this paper, my main focus will be on Musgrave’s realism. However, I will emphasize epistemological aspects of realism. This will lead me to address aspects of his critical rationalism as well.

Much recent discussion in the aesthetics of nature has focused on Scientific cognitivism, the view that in order to engage in a deep and appropriate aesthetic appreciation of nature, one must possess certain kinds of scientific knowledge. The most pressing difficulty faced by this view is an apparent tension between the very notion of aesthetic appreciation and the nature of scientific knowledge. In this essay, I describe this difficulty, trace some of its roots and argue that attempts (...) to dismiss it fail. I then develop a response to the problem, drawing on the notion of the theory-ladenness of observation. I conclude by considering the relationship between this response and one common approach to the problem, the appeal to expressive qualities in nature. (shrink)
